Have you ever wondered why at the same time there are so many different and sometimes opposing theories and power systems? Where did they come from and why are they needed? What is fuss about?
Why are there people professing vegetarianism as the official religion, and it’s impossible to make some of them eat a meat dish even on pain of death? Although, on the other hand, not less, and maybe more people in their daily lives are not able to do without meat, and convincing them to switch to plant foods will not help any of the arguments cited in favor of vegetarianism? Why do systems such as macrobiotic and separate nutrition very strictly regulate the assortment and quantity of food eaten at the same time, while adherents of mixed nutrition never think about it, allowing themselves the most diverse and incredible combinations of dishes and products that are completely unacceptable in macrobiotic or in separate nutrition? Why are the adherents of each of the directions for the most part genuinely convinced that the food system they use is ideal and no one else has the right to claim it? And why, in their opinion, any other theory not only has no right to exist, but also in the most decisive way should be rejected and anathematized?
In my opinion, the answer to these questions lies in a circumstance that is so little appreciated by most people as health, which becomes the highest life value when an illness comes. Revaluation of values ​​occurs because among such categories of human existence as happiness, the meaning of life, beauty and harmony, work and rest, health is an absolute value in all time and geographical coordinates - not subject to devaluation under any system, under any circumstances of life under any social and political cataclysms. When there is no health, everything loses its meaning. No wonder Socrates, the greatest ancient philosopher and life-lover, is credited with saying: "Health is not everything, but everything without health is nothing."
A huge number of people, while they are not sick, are extremely frivolous about their health, especially in matters of nutrition. And evidence of malnutrition is currently becoming widespread such serious diseases as obesity, diabetes, atherosclerosis, gout, and many others, provoked by metabolic disorders in the human body.
Doctors have proven that more than half of cancer is caused by poor nutrition.
Of course, not only food is the culprit of our ailments, as examples can be given when people did not adhere to any dietary rules and their lives were relatively healthy. But there are still relatively few of them, and it is possible that those whom we speak with surprise would live even longer when they would pay attention to their way of life.
And here I would like to note that very many adhere to only those nutritional recommendations that suit them, without thinking about the impending consequences. And all because most of us do not imagine how the body transforms food into energy and into the tissues of the human body. Moreover, even the simplest ideas about the functioning of the digestive system, the role of nutrition and food in this process, the valuable qualities and shortcomings of the most important products are often lacking. Unfortunately, only a serious illness forces us to pay attention to what we eat and how we eat.
And then it becomes clear why, due to insufficient intake of one or another irreplaceable food component, we may develop persistent metabolic disorders, which even stand out in the group of “food-borne disease diseases”. So, if little iron enters the body with food, then anemia - iron deficiency anemia gradually develops in it. With iodine deficiency, the thyroid gland increases, its functions decrease, which causes an endemic goiter. In case of vitamin deficiency, various vitamin deficiencies appear. And vice versa, properly selected nutrition can significantly affect the attenuation of the disease process, up to its reverse development and complete disappearance.
Needless to say, with the help of a well-designed diet, you can alleviate diseases, especially in old age, and often even avoid their appearance. However, even with any pathology, knowledge of specific forms of disturbance of physiological processes occurring in the body is the main condition in the correction of our nutrition.

Sooner or later, everyone finds himself in a situation where he has to seriously think about his diet, if only because by the age of 35-40 every second person has some form of a disease of the gastrointestinal tract. Therefore, a person who is interested in his health should clearly understand what, when and how to eat when a deviation in his state of health occurs. Such information is necessary in order to compose an ideal diet for yourself, which would compensate for the ailments that arise.
However, anyone who, trying to solve the issue of individual nutrition, delves into popular literature, becomes uncomfortable with many theories, systems, recipes and statements on this subject, sometimes the most contradictory and mutually exclusive.
As a rule, such publications give one of many versions of ideal nutrition. Proving its value and undeniable, they practically leave no chance for the existence of any other system, which may be no less acceptable.
It is also confusing that popular literature, in the pursuit of sensation, often extols and passes off original nutritional methods unrecognized by official medicine as a panacea.
At the same time, from time to time as a rage, a fashion arises for some products or, on the contrary, for a total rejection of them. It is not difficult to recall how, quite recently, we were quite seriously persuaded to refuse sugar, salt, eggs, milk, lard, pharmacy vitamins and much more, which I don’t even want to talk about. But times changed, new trends arose, and old prohibitions gave way to them. The head goes around from such recommendations, and it is sometimes difficult for a specialist to figure out who is right, whom to believe and to whom or what to give preference to.
In my opinion, the main drawback of most fashionable nutrition theories, as well as their followers, is that they do not take into account the physiological characteristics of each of us.
The lack of a balanced approach in this matter, ignoring the basic laws of the functioning of the human body, ignorance of the etiology of diseases, and in some cases a lack of elementary endurance, very often leads to newly committed adherents becoming a victim of their own enthusiasm and trying to get away from any one disease, acquire a bunch of others.
In such situations, one should not trust in theories, but in the experience and traditions of one's ancestors. It should be remembered that the truth is somewhere in between, and if moderation is observed, then no benign product can cause harm to health.
The nutritional traditions of different peoples are different, and they evolved over many centuries. Therefore, if you mechanically transfer even the best nutritional characteristics of one people to another, health will not increase, since it will take a lot of time for the gastrointestinal tract of neophytes to adapt and perceive unusual food as their own.
Similarly, different theories and nutritional systems that are ideally suited for one group of people united by some common physiological characteristic or disease (which is not usually mentioned in popular literature) will in no way become ideal nutrition for another group of people, marked by other features or other diseases. And this once again convincingly testifies that we are all different, and what helps one will sometimes not have a positive effect on the other, while the third will simply do harm. Therefore, any, at first glance, the most imperfect nutrition, which however will ideally be suitable for a particular person for his life support in specific conditions, can be considered ideal.
The main purpose of this book, using so-called ideal nutritional systems as an example, such as vegetarianism, macrobiotics, separate nutrition, etc., shows situations when they approach ideal ones, as well as situations in which the same systems become harmful and even dangerous to health . Since there is every reason to consider vegetarianism as the oldest of the concepts, we will begin with it. However, to talk about vegetarianism is not an easy task, because the centuries-old history of the issue has not only resolved it, but rather confused it.
